[PATCH] fdisk: to recognize Intel Rapid Start hibernation partition

[PATCH] fdisk: to recognize Intel Rapid Start hibernation partition

[Jörg Jenderek]

Dear util-linux maintainer,
i use Intel Rapid Start Technology on my PC. According to their 
User Guide "Rapid_Start_Technology_User_Guide_v1.4.pdf"
 i create a partition with id=84 for hibernation by this Technology.

Unfortunately the software fdisk (util-linux-2.27) classifies that partition 
as "OS/2 hidden C:".  That is not wrong, but 
on website https://en.wikipedia.org/wiki/Partition_type is written, that id 0x84
beside using for hiding drive C: this type is a also used as hibernation partition
for Microsoft  APM and also for Intel Rapid Start

So i patched 2 header files so that fdisk recognize this partition type variation

Sorry that i do this way, but i have no knowledge about git toys.

Hope you can apply my patches in a future version of  the fdisk program.

thanks,
Jörg Jenderek
